• Hard disk formatted, freshly installed Windows 8, but it does not work with the old key

  I had bought a Lenovo Z570 two years back, with Original Windows 7 Home Premium.

  When Windows 8 released in November 2012, I had bought and upgraded online for her.

  I had used the Windows 8 since then. Yesterday, due to various problems, I had to format my hard drive, and when I finally managed to install Windows 8 on my laptop again, it does not allow me to activate windows 8 using my normal key (he says that this key did not work)

  It was the key in the email from the seller, and I have an e-mail, which has a Bill to prove.
  I guess this could be due to the PC 1 by purchase clause, however, it's the same PC (more like laptop). So I do not understand why I would not be allowed to activate the software I used earlier on the same laptop still on the same laptop after installing it.

  Please get to me as soon as possible if there is a solution.

  Thanks in advance.

  Hey! Thanks for your help, but I had refreshed my windows 8 in the meantime and connected to the internet after that. and then when I followed your instructions and run slui.exe, it says that windows is activated. so I guess that the problem is solved.

• Keyboard shortcut for close tab (CTRL + W) does NOT work for PDF tabs. Why? Solution?

  Hello

  I had to use the keyboard rather than the mouse or trackpad pretty much recently due to injury. At the closing of the tabs, CTRL + W seems to do. However, it does not always work. It does not work with PDFs and often on YouTube as well.

  What I've read, it's because of the development of collection of plugins. However, isn't there a way to replace it, because it's pretty heavy from the accessibility point of view?

  Thank you!

  Hello, in regard to a PDF file, you may want to try the extension pdf.js (there could be still some bugs, but it is under very active development) - it makes PDF files with common web technology & shouldn't trap keyboard focus...

• Brush control with CTRL + ALT + click right + mouse/pen movement does not work with the tool liquify (photoshop cc 2015): what should I do?

  Brush control with CTRL + ALT + click right + mouse/pen movement does not work with the tool of liquefy; I can't change the size of the brush or hardness. OS win 7 Professional 64 bit, wacom tablet intuos 6.3.14 - 1 driver s pro, Photoshop 2015 CC worm.  2015.0.1 20150722.r.168

  What are your settings of GPU acceleration?  As I understand it, the Alt right click size and hardness adjust needs acceleration GPU to be turned on, but I have a feeling Brush hardness is always set to easy when using fluidity.  You can still see the quick mask as representation of the soft brush when Alt right click, but you can't change the hardness.

  Is that you can change the brush size and pressure (framed in red in my screenshot) Alt right click drag left and right changes size and down to pressure changes, and you can see what is happening in real-time by looking at the sign on the right.  It works independently of your acceleration GPU (IME) settings, but you don't get the effect of soft red quick mask.

  

  Does this fit with what you see, or you are not able to change things at all?  If not, then I've always found that fluidity consumes system resources, if you could check the Task Manager > Performance tab to see what kind of RAM and CPU use is using the fluidity.  That's what I see after direction the lens above with a big brush continuously for 10 seconds.  Note This is on a fairly quick NLE System.

• keyconfig does not work with FF 24.0. Is there a way?

  I just finished rebuilding my PC from a hard drive format. In doing so, I loaded the last 24.0 FF.
  Part of my essential app is a script used keyconfig causes a single copy to send the source page to the Clipboard, where the script analysis. Unfortunately, keyconfig does not work with FF 24.0.

  Writing for easy copy begins to explain how acting on a combination of keys, rather than the action of the mouse, without the use of keycopy - but then told how he has no need, because it's too much effort, and besides - keyconfig exists and does the job - which, I agree, he used, very well - but it is no more.

  What should do? If there is no other way, can I get a downgrade of FF that works with keyconfig?

  There is a new add-on, key config (note the space), but it does not what keyconfig did.

  The end of the thread main support doesn't mention a major problem in Firefox 24: keyconfig 20110522 - mozillaZine Forums.

  Did you install from source: http://mozilla.dorando.at/keyconfig.xpi

  Is the problem that Firefox won't let you activate keyconfig, but the dialog box opens, or you can activate or extension allows you to create shortcuts but they do not work?

  Hello danielbrauer,

  The magnetic site says the requirements are for Windows XP or higher. However, it is not on the Windows Vista or the Windows 7 Compatibility Center.

  You can try the following to see if it will help with compatibility. If the program is not compatible, then you try to install and run the program in compatibility mode.
  Use the following steps:
  (1) right click on the program
  2) click Properties
  3) click on the Compatibility tab
  (4) select run this program in compatibility mode and select Windows Vista or other operating system, the program has been run successfully.

  Check out the link here: make sure to run older programs in this version of Windows
  http://Windows.Microsoft.com/en-us/Windows7/make-older-programs-run-in-this-version-of-Windows

  If this does not help, you can contact the magnet to see if they have an updated version.

  I understand you have questions only by using the back button in the Firefox browser.

  But I would like more information on this topic in order to help you.

  (1) the back button worked before with Firefox?

  (2) don't you make changes before this problem?

  According to your description, there is no problem with the material since it works with Internet Explorer and Google Chrome. Previous key does not only work with Firefox. Therefore, I would advice you to check with Firefox and see if that helps, because they have more expertise on products here to help you better.
